[Q] Class 10 MicroSD Issues

Hello, I bought some day ago a Team 16GB class 10 Micro SD card, but my Defy freeze, expecially when I browse it with quickpic.
I see some thread about class 10 cards and someone found that a partial fix is format with 32k or 64k as file allocation unit size, and maybe another fix is set higher voltage with setsvel.
I've tried the format fix, but I gain only speed, now I'll try the second to gain the needed stability.
I read also that it's an Android kernel related issue, so we still need an official fix.
Someone know some other method?
D_L
Edit: Also the voltage tweak have failed... It's frustrating...

There maybe something related to the manufacturer. For example in my country the cheepest MicroSDHC Cards are made by Adata and Serioux (there maybe other chinesse brands but these are present at known big IT stores).
So people bought them, especially Adata ( which should be better than Serioux).
Class 6/10... and they ended up not working.
So my advice is to try with a Knigston/Kingmax/Transcend/ Sandisk( not that cheap) same 16gb and same class, see if you see a difference.
And i think Class 6 is enough... if let's say Class 10 from the manufacturers above it too expensive.
Maybe it helps.

Transcend?? um.. i don't think so, it's just the same.
perviously i had Transced 8 GB class 6,
using my old galaxy android, it's so fine and speed is good.
but after went to Defy, it was horrible.
often to cause hangs!
have to unmount / remount, which often not succeed, and have to pull out battery.
and it's especially happen when taking picture with camera or downloading + listening to mp3.
many good moments missed, can't take picture, because have to pull out the battery,
and that's embarassing, in front of my friend.
they think i have a smartphone but often hangs,
and now i know it is just because highclass sdcard.
i am using class 2 sdcard now, never get hangs.
end of problem.

I had the same problem.
I bought a 16GB class 10 SDHC ab. a month ago and when I'd been using my Defy always been freezed when I opened the Gallery or any else card related application.
I deleted the partition on the card and created a new one without LBA mode and the problem had been solved temporary. After a week it was start to make freezes again.
Actually I'm using a 16GB class 2 one (I bought it for 15 pounds as used). There's no problems any more, and it works as the same speed as the class 10 one (by the SD Tools).

I gave up and went back to a class 6 8GB Samsung, i did start a thread on the official Motorola forum if you want to go let them know about the problems, it might get them to issue a fix if more people start to complain about it. https://supportforums.motorola.com/thread/53050?tstart=30

i tot only me..
same here..
wanna sell my DNA 16GB class 10.
phone hang quite easily after change to this

So i want to buy a 8 gb card class 4 or 6 tomorrow... and it must work would CM7 . What to get ? I understand that using Sd booster or CM7 default i should get the same speed acordingly to what i set ?

Hi Deonix.
My SD is a SanDisk 8GB class 4 and working well.
A couple days a go i try to use my other SD 16GB (class 10) and had issues, so i back to the 8GB class 4.
Some users have 16 and 32GB class 2 and 4 and they have no problems.

Thanks... i will choose a class 4 probably Kingmax. Anyone with working Class 6 8gb? what manufacturer?
Question: i will have on my 8 gb card a bunch of apps-30-40... some games including Asphalt 6 < for example>, MotoNav, and music. Out of this i think i will still have 2-3 Gb free . I don't need to transfer data from Card to PC frequently (fast i mean) maybe when it happens i will use the phone as a mass storage.
The question is: Do i need a class 6? I only need to work properly while in the phone and have a decent speed as a Mass storage from time to time.

definetely is not cm7 problem,
i thought it was.. and many people thought it too.
maybe it's froyo kernel seems little bit buggy with hiclass sdcard.
and cm7 using froyo kernel though.
using class 2 sdcard is perfect.
the speed is just the same though.
have been checked with some bencharking tools.

Both me and the missus are using class 6 samsung cards this one to be precise http://www.amazon.co.uk/Samsung-Micro-Speed-memory-Class/dp/B002WGIV10/ref=pd_rhf_shvl_44 and it works greatSD tools shows a write speed of around 10MB/s and a read speed of around 21MB/s

actually, i'll buy SD Card Team 16 Gig class 10..
any problem with froyo for class 10 ?
need more advice from u guys

many people confirm there's a problem with that,
even with 6 class sdcard.
i don't know what's going on but it's happening and annoying,
it happens on froyo, and CM7 too (FYI, CM7 Quarx uses froyo kernel).

Thats what we are all saying, class 10 cards seem nothing but a problem regardless of size. This is why i went back to the class 6 samsung and posted a link to it cos i know it works.

Just bought a 8 gb Kingston class 4. Will report speed and any other issues as soon as i install CM7 with it.
Hope it works well. It's an Android Kernel issue from Froyo on the Class 6/10 crashes as i can understand.. nobody's fault ( here on XDA i mean). Still some work.
Also i remain strong on my position.
Choose your manufacturer wisely even if it costs 10-20$/i dunno how much more.

I use kingmax 16gb class10 allways hang,
so bad,
use class 4 or 2 batter

i nearly bought a 16GB Lexmark class 6 card today but i dare not in case it didnt work, this is a crap situation.

Same here - Froyo 2.2.2 and Transend 16GB Class10 - freezes at random basis and random applications. No issues with 8GB Class 4.

I have similar problem, how do I know the class of the card? It is I believe a Kingston, I've had it for ages.
Also if it is relevant to someone, I have a Defy from CEE distribution, with Froyo.

You can check if the class is printed on the card. Usually it is a number inside a letter "C" (like a full circle).

[Q] 32GB SD-Card with Wildfire S?

This ones got me a little confused.
Both my younger siblings have the Wildfire S that came with 2GB SD cards - these both work fine.
We've fitted 32GB cards into both the phones and my brother in particular repeatedly received the dreaded "SD Card unexpectedly removed".
Today, my Sister also claimed to have the same issue.
I've spoken to HTC who after several minutes of searching for an answer could only say they haven't tested 32GB cards with the HTC Wildfire S and that we'd need to test it with 16GB cards first.
Are HTC being straight with me by saying that the Wildfire can only support 16GB cards properly or is there something else at fault here?
Both cards were from bought at play.com.
Thanks.

I've got the same problem than you. And my SD card is only a 4Go one...
But, after a second try, it works.
I think it comes from the quality of the card (writing speed may be ?).

Format it first in the computer with fat32.

I've formatted the card as FAT32 already via my PC.
It's a 32GB Class 4.

and i have problems with my 32gb class 4 card.
if i connect with my pc, coming error.
have fotmat it with pc and with phone.
no any chance.
now i using a 16gb class 4

Class 4 for a 32gb is too slow, you need at least a class 6

I think 2.3.5 kernel source is not yet released in htcdev.com only available is 2.3.3. I havent checked. Also we need a new working data2sd for 2.3.5 cause old one dont work. If anyone finds a working one PM me so we can make a new sense ROM and other mods you like.

edit I just checked its already available. I'll see what I can do. hmm. expect 2.3.5 OC kernel in a few days. got to find a pc now for ubuntu to compile kernel.

I also have a 32G class 4 card in my WFS. Never had any problems with it.

Sandisk 32Gb Class 4 seems to work for me
I've just swapped the Samsung 2Gb SDHC card that came with my Wildfire S for a 32Gb Class 4 Sandisk SDHC card that my wife's aunt bought me for Christmas.
I've not used it much, and I'm unlikely to press it with video, but it's played the music that I restored to it (from a backup of the 2Gb SDHC) and it still has 29.7Gb free for more music (one of the main reasons for getting the phone and asking auntie for a 32Gb SDHC card for Christmas)

i hv d same issue with all cards...then i tried class2 and voila....its workd...i previously tried class 4 4gb...nw i m running 8gb class 2 ...so i thnk it supports only class 2 or smthg else...i hv also installed sd speed increase

[Q] Can a faulty SD Card influence a rom performance ?

Hi guys, i've found out my sd card might be faulty since i get laggs on all Sense roms or any other that requires an Ext partition to use A2SD or D++. I've been trying and trying to use SGBS roms but i get a laggy performance. Now my question is, how can an sd card influence a rom performance ?
Atm im using the default class 2 (i get similar problems probably a bit better with this card) that came with the phone but the other one was a TEAM 4gb Class6.

Mate I think the class 2 is why you are getting lag, you're meant to use at least a class 6 from a reputable brand
Sent from my CM7.1 Desire using XDA Premium App

What brand do you recommend for the desire ? i want at least a class 6

My class 2 works smoothly.

Type of partition alignment and formating of a card greatly influences the speed of data2sd/a2sd roms.. You can see a discussion and possible solution discussed In the supernova thread recently

what micro sdhc card do you have in your defy? what class?

Change memory card. Don't use class10. Defy work best on class2, class4 or class6.
If problem persist. Wipe data and cache in stock recovery will do the trick.

Try using the card that came with defy. If it works as it should then buy your self a bigger card if you need one, but remember, don't buy class10, class4 is just fine.

Actually it does make sense.
This issue is a bug in Motorola rom, CM7 has this corrected.
I couldnt for my life use for more than 3 days my 16gb Sandisk card, I would always get errors, phone rebooting, pics not saving, "please format your card" or "card damaged" messages, etc, while using Stock or early CM7 roms.
After they introduced the fix, no more card issues. Been using my 16GB card for months now

thanx mate i would definately do that...

Yep! those are two different issues. One is with Class10 cards, but I have seen that issue on other phones too. The other is a Moto issue.
Regarding modding the defy, you can mod it and not lose warrranty, just read the Beginer's Guide I wrote here on XDA
And @ans39, try using Panasonic SD Formatter.

I dont know, I have never had any of the issues you are mentioning, and I'm running CM7.1 Stable since it went out and every RC version since they went out. It has always worked good for me.
CM7.1 for the Defy is the second most installed CM version, only the Bravo (Desire) and only a bunch of them actually have issues soooo...
MIUI is closed source too, I dont thrust them that much

[Q] Help needed regarding SD card...

I bought a new sd card.. samsung 16gb class 6 .. I partitioned it using 4EXT recovery but it was giving me problems with seb's rom and Alex's bliss droid pvteam mod as well.. I tried gparted .. it didn't help too..
Seb's rom works for a while but later it started giving me freezing problems and Alex's bliss droid pvteam mod rom stucked even at the first boot..
Then i exchanged the card with the dealer for sandisk 16gb class 4... its giving me the same problems.. I can't seem to properly partition it i guess..
and weird part is that there is no such issue with my old 8gb sandisk class 2 card... both ROMs run smoothly on that one... I just can't figure out what's wrong..
Please help... I feel like I wasted my savings on a new sd card for nothing...

If you mean by "freezing" the phone takes seconds to respond to opening an app. Yes i had the same with my class4 danelec SDcard. Switched to Verbatim microSDHC 16 GB (Class 10) and now my freezing is gone. Only 1 app is still taking a 2 or 3 seconds to respond, and that is whatsapp.

I mean the total freezing of the phone.. not just any app.. the phone freezes... you just have to pull the battery out nothing else works...

I see two reasons for this:
a) the partitions on your sdcard are wrong (I had the issue when a vital ext4 partition was too small)
b) the sdcard itself?
Some hints:
a)
(make a nandroid backup before you change your sdcard partitions)
recheck your partitions
make them all primary
when you repartition the card, reflash
b)
I've used SanDisk 32GB class 4 for more than 1 year...reliability is excellent and speed is good. I rather spend more money on a good sd card than having the risk that the phone 'hangs' or i lose data from my phone.
